Would like to know some experiences with using Music on hold within a large enterprise network over 10,000 phones.
What is the best practice to implement music on hold, should you use dedicated unicast music on hold servers or implement multicast in the network.
What experiences have customers faced when using a service provider MPLS network. Did the service provider allow multicast over their network or did the customer use unicast or GRE tunnels between the customer edge routers to allow multicast to the customer edge.
I have heard that you can use third party music on hold solution where you connect a music server to an FXS port on the router which is centrally managed by a music on hold server connected to the call manager via JTAPI.
Appreciate any experiences relating to best practice music on hold for large enterprise.
